ROCHA, Dayane Silva et al. Potential Antimicrobial and Chemical Composition of Essential Oils from Piper caldense Tissues. J. Mex. Chem. Soc [online]. 2016, vol.60, n.3, pp.148-151. ISSN 1870-249X.

The essential oils from leaves, stems and roots of Piper caldense were analyzed by GC-MS. The antibacterial potential of the oils was evaluated against gram-negative bacteria and gram-positive bacteria. The major chemical constituents that were identified from various parts of this plant were α-cardinal, α-muurolol, tujopsan-2-β-ol and δ-cadiene in the leaves, valencene, pentadecane, elina-3,7-11-dieno α-terpineol in the roots and terpine-4-ol, α-terpineol, α-cadinol 2-β-ol in the stems. Tissue oils showed antibacterial activity against the bacteria tested except for Enterococcus faecalis. This is the first report of the biological activity and chemical composition essential oil of P. caldense.

Keywords : Piper caldense; Piperaceae, essential oil; antimicrobial activity.
